We have already seen that the concepts of reasonable and unreasonable frequently depend on whether you adopt God’s point of view or man’s: what is intelligent for one is folly for the other. On the other hand, as I have said, not only do men not agree as to what is and what is not reasonable, the only thing they do agree on is the indisputable truth that the Gospel is madness; outright insanity, if we want to speak clearly. Nevertheless, for God things are well known: the imagined wisdom of the world is foolishness, while the Gospel is the only craziness that makes sense. This is tantamount to saying that the only thing reasonable for God is precisely the attitude that we would qualify as being crazy.

It would be trivial to consider that what we have just said is a pun. The problem is too serious to dismiss it in such a way. There is still argument as to who was really crazy, Don Quixote or those around him. It is not too clear that Cervantes made the best decision, having Don Quixote die in his bed, surrounded by his friends and with his sanity recovered. There are even those who ask themselves if this sanity was indeed more reasonable than his madness. Either way, is it not true that we feel a certain nostalgia for something indefinable when we read that Cide Hamete Benengeli finally lowers his quill after telling us, as if giving a happy ending, that Don Quixote died after having recovered his reason, thereby returning us, without actually saying it, to the world of sane men? Probably we have all had the presentiment that somehow, in light of the supposed sanity of the world, there may be some kind of craziness more reasonable than what we see every day. A craziness, also, that is more necessary for man than that which the world usually considers as intelligence. Maybe that is why the audacity of Erasmus in his Praise of Folly seems almost logical. Man indeed had gone mad because of sin which, in turn, was caused by a lack of love. After that, only another madness, though now of overabundant love, could bring him back to the path of sanity. Or, in other words: a madness of love capable of curing the supreme foolishness of that lack of love: For, seeing that in the wisdom of God, the world, by its own wisdom, knew not God, it pleased God, by the foolishness of our preaching, to save them that believe (1 Cor 1:21).^. It seems clear that it is impossible to solve the dilemma of what is and what is not reasonable without keeping in mind what God has done for man and what He has taught him.
